DISCUSSION
THROUGH MONDAY...
BEHIND THE SHOWERS OVER THE EAST THIS MORNING, PRESSURE RISES
WORKING INTO THE REGION BEHIND THE PACIFIC TROUGH WERE BRINGING
GUSTY WESTERLY WINDS TO THE AREA. STRONGEST WINDS HAVE BEEN OVER
THE WESTERN FOOTHILLS WHERE GUSTS TO 50 MPH HAVE BEEN OBSERVED.
EXPECT THE WINDS TO CONTINUE THROUGH THE AFTERNOON, BACKING OFF
THIS EVENING. ANOTHER WAVE CURRENTLY IN OREGON WILL SLIDE EAST
THROUGH IDAHO AND WYOMING THIS EVENING AND OVERNIGHT, KEEPING
MOUNTAIN SNOW SHOWERS IN THE FORECAST FOR SOUTH AND WEST ASPECTS
OF THE BEARTOOTH/ABSAROKAS AND SOUTHERN BIGHORNS. ACCUMULATIONS
WILL BE LIGHT OVERALL, BUT A FEW INCHES ARE POSSIBLE IN THE
MOUNTAINS OUTSIDE COOKE CITY. A FEW SNOW SHOWERS MAY CLIP FAR
SOUTHEAST MT LATE TONIGHT INTO EARLY TOMORROW MORNING, BUT THE
MAJORITY OF THE ENERGY WILL REMAIN TO THE SOUTH.
WEDNESDAY INTO THE FIRST PART OF THE WEEKEND, THE PATTERN LOOKS
TO TRANSITION TO SOUTHWEST FLOW ALOFT OVER THE REGION AS TROUGHING
DEVELOPS ALONG THE WEST COAST AND RIDGING NOSES IN. DRY
CONDITIONS WILL PREVAIL INTO FRIDAY, BEFORE ENERGY ADVECTING IN
FROM THE SOUTHWEST BRINGS A RETURN OF SNOW SHOWERS TO THE WESTERN
MOUNTAINS LATE FRIDAY INTO SATURDAY. BREEZY CONDITIONS CAN BE
EXPECTED AT TIMES, BUT STRONG WINDS ARE NOT EXPECTED. HIGH
TEMPERATURES ARE FORECAST FROM THE 40S TO 50S MOST DAYS, WARMEST
ON WEDNESDAY AND SATURDAY. WHILE STILL AWAYS OUT, THERE IS
POTENTIAL FOR MORE UNSETTLED CONDITIONS LATE SUNDAY INTO EARLY
NEXT WEEK AS ENSEMBLES AND CLUSTERS PROG A LARGE TROUGH AND
ASSOCIATED LOW TO PUSH INLAND INTO THE ROCKIES. THIS COULD BRING
COOLER CONDITIONS AND PRECIPITATION TO PORTIONS OF THE REGION. STP
AVIATION
BREEZY WEST WINDS WILL CONTINUE ACROSS THE REGION THROUGH THE
AFTERNOON WITH GUSTS 30-45 KTS POSSIBLE (STRONGEST AT KLVM, K6S0,
K3HT). SNOW SHOWERS ACROSS THE ABSAROKA-BEARTOOTHS WILL LIKELY
KEEP MOUNTAIN OBSCURATIONS IN PLACE INTO THE OVERNIGHT HOURS. TS
